Neosporosis is a widespread parasitic disease caused by Neospora caninum, an intracellular protozoan parasite. It causes economic losses due to reproductive failure. The potential relationship between pregnancy outcomes and levels of IFN${\gamma}$, hormones, and antibodies in naturally N. caninum-infected cows was examined in the blood samples collected every 2 or 4 weeks in 26 pregnant cows from 4 different farms. The mean S/P value of seropositive nonaborting animals (n = 14) reached peak levels 15 weeks prior to parturition, and declined thereafter to parturition. The S/P value 13 weeks prior to abortion in seropositive aborting cows (n=3) remained at high levels, and abortions occurred at 20 (142 days), 26 (185 days), and 28 weeks (199 days) after artificial insemination. IFN${\gamma}$ levels in the seropositive non-aborting group varied by individuals and gestational periods; IFN${\gamma}$ levels stayed at elevated levels or increased abruptly close to abortion in seropositive aborting cows. IFN${\gamma}$ level patterns in the seronegative group (n = 9) were similar to the seropositive non-aborting group, although IFN${\gamma}$ amounts were lower than the seropositive group. The mean progesterone levels in the seropositive non-aborting and seronegative groups decreased markedly 7 weeks prior to parturition. The mean progesterone levels 5 and 7 weeks prior to abortion were lower than the other groups 5 and 7 weeks prior to parturition. The mean 17${\beta}$-estradiol levels in the seropositive aborting cows increased close to abortion; the produced amounts were lower than those of seropositive non-aborting and seronegative groups close to parturition. These results suggested that lower levels of progesterone and ${\beta}$-estradiol in Neospora-infected cows may lead to increases in IFN${\gamma}$ production and in turn may result in abortion.
The purpose of this study was to evaluate the level of biomedical ethics awareness, empathy among college students. The participants were 469 university students in South Korea. The average score for biomedical ethics awareness was $2.89{\pm}.21$ ; The average the scores of empathy was $2.41{\pm}.35$. Biomedical ethics awareness showed a positive correlation with empathy(r=.203, p<.001). Emotional empathy showed a significant effect on biomedical ethics awareness. And the empathic concern of emotional empathy showed a significant effect on right to life fetus, artificial abortion, artificial insemination, prenatal diagnosis of fetus, right to life of newborn, euthanasia, brain death of biomedical ethics awareness. The results of this study suggest that biomedical ethics education to the emotional empathy should need for general university students.
The purpose of this experiment is to compare the pregnancy rate (PR) according to the state of the ovaries and uterus, according to the number of embryos transferred from cows and heifers and to investigate the method of artificial twin induction with Hanwoo $in$$vitro$ fertilized (IVF) embryos by embryo transfer (ET). Looking at the PR according to the condition of the ovaries and uterus, the result was not influenced by the condition of the ovaries, but was significantly influenced by the state of the uterus. The PR according to the number of embryos transferred from cows was 36.8%, 53.0%, 50.5% for 1, 2, and 3 embryos respectively, and although there was a higher frequency of twin calves with 3 embryos than with 2, the calving rate was the highest with 2 embryos. In case of heifers, the transfer of 1 embryo showed the best pregnancy and calving rate, and although the PR was similar with 2 embryos (67.7 versus 66.4), in case of 2 embryos transferred there was high frequency of embryonic loss( 6.1%) occurred when a cow was diagnosed at 28 and 53 d after ET, total loss (21.3%; sum of fetal death, abortion and stillbirth after pregnant diagnosis at 60 day).

Objectives: The purpose of this study was to provide substantial foundation to establish effective sex education plan for university students, and to inquire into sexual knowledge, consciousness and values of university students and into whether there are difference between health related major subjects and non-health related major subjects. Methods: This study was conducted on students in 227 health related major subjects and 226 non-health related major subjects in chungbuk C city. The Questionnaire, used in this study, was re-made on basis of reviews and previous studies, and total of 453 questionnaires were used. Results: Sexual knowledge scores were not significantly difference between health related major subjects and non-health related major subjects. but health related major subjects were more educated contraception, pregnancy artificial abortion, sexually transmitted disease than non-health related major subjects. Sexual knowledge was correlated with attitude in sex, times of sex education and usefulness of sex education. Conclusion: The university authorities make a curriculum for systematic sex educations and need to assertive support students and they can have right sexual consciousness and have mature and responsible attitude to sex through right education of knowledge in sex.
This study sought to provide basic for the establishment of desirable sense of ethics values by analyzing the consciousness of biomedical ethics of freshmen nursing students. The subjects of the study were 420 freshmen nursing students. The period of data collection was from April 1 to 6, 2012 and collected data were analyzed on SPSS/PC 19.0 program. The results is followed; First, the mean score of the consciousness of biomedical ethics was $2.39{\pm}0.25$. While the mostly high ranked category of biomedical ethics was the right to life of newborn($2.76{\pm}0.39$), the category with the lowest score was the artificial abortion($2.13{\pm}0.39$). Second, with respect to the characteristics of participants there were statistically significant difference in total score according to age, religion, and participation in religious activity, experience of hearing for biomedical ethics, sources of information for biomedical ethics, ethical values for biomedical ethics, and in intention to attend biomedical ethics in subjects. As a result, an arbitration program that could promote either changeable or controllable ethical values must be considered with attention to the significant variables that can promote the consciousness of biomedical ethics of freshmen nursing students.
The purposes of this descriptive study were to identify the prevalence rate of urinary incontinence(UI) and the differences in frequency of incontinent and normal women by general characteristics, obstetrical history, and the conditional events for urinary incontinence of the elderly women in a community. By the results of this study, it is intended to provide nursing practice guidelines for incontinent women. The research design of this study was a preliminary descriptive study. The 173 subjects were 55 years old and over, and resided in a small city area. Data were collected from June 20 to July 20, 2001, by an interview or a self-report with questionaire. The questionaire was composed of items of general characteristics, obstetrical characteristics, and conditions of UI by the modified Henderickon's Stress Incontinence Scale(1981). The results were summariezed as follows: 1. The UI prevalence rate of the sample was 64.2%. Of the incontinent women, 31.5% had experienced UI for a period of three to five years, and 84.7% had never treated or managed their UI. Frequency of UI was once or twice times per month(46.8%). 2. The total mean of UI on the scale in the incontinent women was 25.50 of 85, ranging from 18 to 41. 3. The most frequent condition of UI was coughing, followed by laughing, sneezing, heavy exercise, and preparation of urination in descending order. 4. There were significant differences in age, education, social activity, and urinary difficulty between the incontinent women and the normal women. 5. There were significant differences in frequency of spontaneous abortion, age of menopause between the incontinent women and the normal women. 6. There were no significant differences in number of delivery, frequency of artificial abortion, age of the last delivery, and postal health management between the incontinent women and the normal women. In conclusion, the incidence of UI in this study was high, but there were no effective treatments or management. It is suggested to provide the adult women with knowledge about UI, and to educate preventive behavior and control skill of urinary incontinence. Also episodes of urinary incontinence were high in the situation of sudden increase of abdominal pressure. This data can be used for the prevention strategy of urinary incontinence, In future research it is recommended to identify comprehensive factors related to urinary incontinence including psychosocial factors, and effective strategies of urinary incontinence.
Somatic cell nuclear transfer (SCNT) for miniature pig has been developed for xenotransplantation and many other biomedical experiments. However, the efficiency of SCNT is still very low due to many factors. To optimize the surrogate mother condition for improvement of cloned miniature pigs efficiency, we investigated the effect of the status of surrogate mother on pregnancy, farrowed rate in SCNT pigs. After SCNT with mesenchymal stem cells as donor cells, the SCNT embryos were surgically transferred into the oviduct of surrogated pigs. To compare the effects of status of surrogate pigs on pregnancy, surrogate pigs were prepared by artificial abortion at day 20~29 (Group 1), 30~39 (Group 2), and 40~45 (Group 3) of gestation. After SCNT embryos transfer in three different status of surrogate pigs, Group 2 (56.3%) and 3 (55.6%) had significantly ($p$ <0.05) higher the pregnancy rate than group 1 (0%) at day 30 of gestation. The status of ovulation in surrogate pig also was investigated. Post-ovulation status (54.8%) had higher proportion than pre-ovulation status (38.7%) and ovulation status (6.5%). We obtained 19 cloned miniature piglets from seven surrogate gilts and five piglets are living healthy but fourteen piglets died soon after birth or stillbirth. The weights of piglets greatly differ from 254 to 1,296 g. Microsatellite analysis showed that cloned piglets were genetically different from the surrogate mother and cloned piglets were genetically equal to the donor cell. In conclusion, the present result indicates that artificially abortion method can improve the efficiency of pregnancy after SCNT in pigs. This study will provide available method for the further study and application in the field of xenotransplantation.
This study was undertaken for the clinical evaluation and statistical analysis on the 88 women with histopathologically confirmed ectopic pregnancies who were admitted and treated from grand opening on May-28, 1983 to Sept.-30, 1985. Incidence of ectopic pregnancy was 1 in 22.2 deliveries and the most common age group was in 30~34 years of age. There was tendency of decreasing incidencies as the gravidity, panty or artificial abortion were over 3. The most common etiologic factor was pelvic inflammatory disease and procedures for family planning were the next common. Common symptoms were lower abdominal pain (85.2%) and vaginal spotting (56.8%). At the admission, hemoglobin level under 10gm% were 44.3%, 69.5% of urine HCG tests were positive. Culdocentesis was positive only in 75.9%. Termination was frequent at 6 ~ 7 weeks of gestation mostly with rupture or abortion. Free blood in the abdominal cavity was averaged 1,224 ml. 4 cases of clinicobiochemically suspected ectopic pregnancies with spontaneous regression were excluded, and there was no fatal case treated in hospital.
This study was conducted to investigate the breeding status of farms to improve the production efficiency of Hanwoo calf. The study was conducted on 45 farms divided into two groups. This study was conducted to investigate the breeding size and breeding area of Hanwoo cows. The average age at first delivery of Hanwoo was 28.7 months. The number of artificial insemination per pregnancy was $1.45{\pm}0.32$, and the number of artificial insemination days after birth was 119.8 days. Conception rates were $75.2{\pm}16.93%$ for small farms and $70.6{\pm}17.46%$ for medium sized farms and $71.4{\pm}11.03%$ for large farms. When we looked at farming methods, 'the farmers using estrus observation aids' had 10.42% higher calf production rate than the 'unused farmers'. The farms vaccinated with IBR and BVDV for breeding cattle showed a 4.41% decrease in abortion, stillbirth and mortality. According to farming conditions, conception rate and delivery rate improved by 3.47% and 18.29%, respectively, when grazing and exercising were performed. Observation, immunization and grazing were found to be important indicators for improving calf production efficiency in Hanwoo farm. This study can be used as a research data to improve the reproductive rate of farmhouse sites through the survey on the breeding status of Hanwoo farmers.
